FIELD OF THE INVENTION

The present invention relates to lighting systems that selectively emit light containing specific wavelength ranges and layers responsive to the emitted light, and associated methods.

BACKGROUND OF THE INVENTION

Making a picture, character, or otherwise identifiable image appear on a surface has usually involved the projection of the image on an otherwise blank surface. Moreover, the progression of a sequence of images, such as simulating motion, has tended to include either a series of projecting devices working in sequence to project the images, or a single projecting device that moves or rotates. However, such systems typically require the environment in which the image is to be perceived to be relatively darker, or the image may be difficult to perceive. Moreover, the projection of an image onto a non-blank surface makes the image difficult to recognize.

Images have been embedded in random, pseudo-random, or otherwise non-recognizable patterns. This is useful for entertainment, where an image becomes apparent where it once was not apparent. For example, autostereograms are well known. However, prior embedded images have typically relied on biological responses, such as the decoupling of eye convergence, in order for the embedded image to become apparent, and not all observers are able to accomplish such decoupling. Other systems rely on a filter to be positioned intermediate the embedded image and the observer, usually in the form of eyewear. These systems are generally undesirable, as the eyewear is not conducive to ordinary activities. Accordingly, there is a need for a system for eliciting embedded images without impeding the activity of the observer, and that is readily observable by all observers.

This background information is provided to reveal information believed by the applicant to be of possible relevance to the present invention. No admission is necessarily intended, nor should be construed, that any of the preceding information constitutes prior art against the present invention.

SUMMARY OF THE INVENTION

With the foregoing in mind, embodiments of the present invention are related to a system for accenting a region of a layer comprising a lighting system that includes a plurality of light sources and a layer configured to be applied to a surface of a structure. The layer may include a first region having a first surface scatter profile and a second region having a second surface scatter profile. The light emitted by the plurality of light sources may combine to form a polychromatic combined light. Additionally, the first surface scatter profile may be configured to diffusively scatter a combined light including a first wavelength. Furthermore, the second surface scatter profile may be configured to diffusively scatter a combined light including a second wavelength. The combined light may be at least one of a first polychromatic light including the first wavelength and excluding the second wavelength and a second polychromatic light including the second wavelength and excluding the first wavelength.

Another embodiment of the present invention is related to a system for accenting a region of a layer comprising a lighting system that includes a plurality of light sources and a computerized device operably connected to each of the plurality of light source. The computerized device may be configured to individually operate each of the plurality of light sources. The lighting system may further comprise a layer configured to be applied to a surface of a structure. The layer may comprise a first region and a second region, wherein each of the first region and the second region have a surface scatted profile configured to diffusively scatter a combined light including a first scattering wavelength. The plurality of light sources may comprise a first light source positioned generally adjacent to the first region and a second light source positioned generally adjacent to the second region. The light emitted by the first light source may not be incident upon the second region and light emitted by the second light source may not be incident upon the first region. The computerized device may be programmable to selectively operate the first light source and the second light source such that only one of the first light source and the second light source emits light comprising the first scattering wavelength at a time.

Another embodiment of the present invention is related to a system for accenting sub-surface regions comprising a lighting system substantially as described above. A first appliqué may be formed into a first image and adapted to be applied to a surface such that light from the first light source is incident thereupon and light from the second light source is not incident thereupon. A second appliqué may be formed into a second image and adapted to be applied to the surface such that light from the second light source is incident thereupon and light from the first light source is not incident thereupon. Each of the first appliqué and second appliqué may be configured to diffusively scatter a scattering wavelength within the visible spectrum. The computerized device may be configured to selectively operate the first light source and the second light source such that only one of the first light source and the second light source emits light comprising the scattering wavelength at a time.

Another embodiment of the present invention is related to a system for accenting sub-surface regions comprising a lighting system substantially as described above. Again, a first appliqué may be formed into a first image and adapted to be applied to a surface such that light from the first light source is incident thereupon and light from the second light source is not incident thereupon. A second appliqué may be formed into a second image and adapted to be applied to a surface such that light from the second light source is incident thereupon and light from the first light source is not incident thereupon. Each of the first appliqué and second appliqué may include a color conversion material configured to convert a source light including a source wavelength into a converted light including a second wavelength within the visible spectrum. The computerized device may be configured to selectively operate the first light source and the second light source such that only one of the first light source and the second light source emits light comprising the scattering wavelength at a time.

Yet another embodiment of the present invention is related to a layer that is applicable to a surface of a structure comprising a pseudo-random pattern comprising at least one of a variety of shapes, a variety of colors, and a variety of textures. A first region may have a first surface scatter profile that diffusively scatters a combined light comprising a first wavelength, and a second region having a second surface scatter profile that diffusively scatters a combined light comprising a second wavelength. Each of the first region and the second region may be configured to diffusively scatter light so as to depict an image embedded in the pseudo-random pattern. The image depicted by the first region may not be observable when light incident thereupon does not include the first wavelength, and the image depicted by the second region is not observable when light incident thereupon does not include the second wavelength.

Another embodiment of the present invention is related to a method of using the above system that may comprise the steps of emitting a first combined light including a first wavelength equal to a diffuse scattering wavelength of the first region and excluding a second wavelength equal to a diffuse scattering wavelength of the second region. The method may also include diffusively scattering the first combined light from the first region, emitting a second combined light including the second wavelength and excluding the first wavelength, and diffusively scattering the second combined light from the second region.

Still another embodiment of the present invention is related to a method of accenting a region of a layer. The method may comprise the steps of providing a layer comprising a pseudo-random pattern having embedded therein a plurality of regions. Each region may have an individual surface scatter profile configured to diffusively scatter an individual light wavelength, and each region depicting one image of a sequential series of images, and emitting a sequence of polychromatic light. Each polychromatic light may include one individual light wavelength that is diffusively scattered by one of the plurality of regions. The sequence of polychromatic light may be configured to correspond to the sequential series of images.

An embodiment of the invention, as shown and described by the various figures and accompanying text, provides a system 100 comprising a lighting system 200 and a layer 300, as shown in FIG. 1. The lighting system 200 may be configured to emit light having certain characteristics of light that interact with certain regions 302 of the layer 300 to accent those regions.

The lighting system 200 may comprise a plurality of light sources 202. The plurality of light sources 202 may each be a light-emitting device configured to emit light having certain light characteristics. Examples of light characteristics that may be controlled in the emission of light include wavelength, luminous intensity, color, and color temperature. Moreover, each light source 202 may be configured to emit monochromatic light or polychromatic light. Additionally, the plurality of light sources 202 may include a type of light source, including, but not limited to, an incandescent source, a fluorescent source, a light-emitting semiconductor such as a light-emitting diode (LED), a halogen source, an arc source, or any other light source known in the art. More information regarding the operation and characteristics of the plurality of light sources 202 may be found in U.S. patent application Ser. No. 13/709,942, the entire contents of which is incorporated by reference hereinabove.

Continuing to refer to FIG. 1, the layer 300 will now be discussed in greater detail. The layer 300 may be a layer of material configured to be applied to the surface 402 of a structure 400. Furthermore, the layer 300 may include one or more regions 302 that are configured to interact with light emitted by the lighting system 200 so as to be accented. In some embodiments, the layer 300 may comprise a first region 302′ and a second region 302″. The first region 302′ may be configured to have a first surface scatter profile. More specifically, the first region 302′ may be configured to reflect, scatter, diffusely reflect, diffusively scatter, or otherwise redirect light within a scattering wavelength range and absorb light outside the scattering wavelength range. Furthermore, the first region 302′ may be configured to reflect, scatter, diffusely reflect, or otherwise redirect light having a certain scattering wavelength and absorb light having a different wavelength. The scattering wavelength range and the scattering wavelength may be associated with a color. Similarly, the second region 302″ may have a second surface scatter profile that is configured to reflect, scatter, diffusely reflect, or otherwise redirect light within a certain scattering wavelength range and absorb light outside the scattering wavelength range, or reflect, scatter, diffusely reflect, or otherwise redirect light having a certain scattering wavelength and absorb light having a different wavelength. The scattering wavelength range and scattering wavelength may be associated with a color. Additionally, the first surface scatter profile may be configured to reflect, scatter, diffusely reflect, or otherwise redirect light associated with a color that is also the same as or similar to the color of light that the second surface scatter profile is configured to reflect, scatter, diffusely reflect, or otherwise redirect, or it may be of a different color.

The first region 302′ and the second region 302″ may be positioned anywhere on the layer 300. In some embodiments, the first region 302′ may be positioned at some distance from the second region 302″. In some embodiments, the first region 302′ and the second region 302″ may be relatively near to each other. The distance between each of the first region 302′ and the second region 302″ may be configured based upon the entire length of the surface 402, the sizes of each of the first region 302′ and the second region 302″, the number of any other regions 302 apart from the first and second regions 302′, 302″, or any other configuration. Additionally, the distance between the first and second regions 302′, 302″ may be determined based on a center-to-center determination or an edge-to-edge determination. The above configurations are exemplary only and do not limit the scope of the invention.

Additionally, each of the first region 302′ and the second region 302″ may be configured into a desired shape. In some embodiments, each of the first and second regions 302′, 302″ may be shaped into a representation of a recognizable object, character, ideogram, numeral, or image. In some embodiments, the first region 302′ may be shaped into a representation a first object, character, ideogram, numeral, or image in a sequence, and the second region 302′ may be shaped into a representation of a second object, character, ideogram, numeral, or image in the sequence. It is appreciated that any number of regions 302 may be configured to represent any number of items in a sequence.

The regions 302 may be formed into the layer 300 by any suitable means, methods, or process. In some embodiments, the layer 300 may include a base material 304, and each of the regions 302 are topically attached to a surface 306 of the base material. Examples of topical attachment including painting, adhesives, glues, transfers, appliqués, static cling, magnetism, and any other method of topical attachment are included within the scope of the invention.

In some embodiments, the regions 302 may be configured to have a first section configured to diffusively scatter light within the scatter wavelength range as described herein above, and a second section configured to absorb light within the scatter wavelength range. For example, in some embodiments, a perimeter of the regions 302 may be configured to absorb light within the scatter wavelength range and an interior of the regions 302 may be configured to diffusively scatter light within the scatter wavelength range. In other embodiments, an interior section of the regions 302 may be configured to absorb light within the scatter wavelength range, and the section of the regions 302 surrounding the interior section may be configured to diffusively scatter light within the scatter wavelength range.

The layer 300 may be any material and of any form that may be applied and attached to a surface of a structure, either fixedly or temporarily. Examples of such forms include, without limitations, paints, sheets of material such as wallpaper, wall coverings, structural wall features, and any other forms known in the art.

The lighting system 200 may be configured to include a plurality of light sources 202 that are capable of emitting light falling within the scatter wavelength ranges of each of the first surface scatter profile and the second surface scatter profile. In some embodiments, the light emitting elements of the plurality of light sources 202 may be configured to generate polychromatic light having varying spectral power distributions. In other embodiments, the plurality of light sources 202 may emit light, either monochromatic or polychromatic, that combines to form a combined polychromatic light. In either of these embodiments, the polychromatic light may include within its spectral power distribution light within a wavelength range corresponding to a scatter wavelength range associated with one of the first surface scatter profile and the second surface scatter profile, or both. Furthermore, the polychromatic light may be perceived as a white light by an observer.

In some embodiments, the plurality of light sources 202 may be positioned in an array, the array being positionable adjacent to a ceiling. In such embodiments, the layer 300 may be attached to a surface of a wall such that light emitted by the plurality of light sources 202 is incident upon the layer 300.

When the polychromatic light is incident upon the first region 302′ and the second region 302″, each of the wavelengths included within the spectral power distribution of the polychromatic light will be either absorbed or reflected, scattered, diffusely reflected, or otherwise redirected by each of the regions. More specifically, when the polychromatic light includes a wavelength within a scatter wavelength range associated with one of the first region 302′ or the second region 302″, or both, the associated scatter wavelength range will be scattered, while the remainder of the spectral power distribution will be absorbed. Accordingly, the light within the scatter wavelength range will be reflected, scattered, diffusely reflected, or otherwise redirected into the environment and observable. Moreover, where the region 302 that is scattering the light is shaped to represent an object, character, ideogram, numeral, or image, that representation will similarly be observable. Correspondingly, when the spectral power distribution of the polychromatic light does not include light within a scatter wavelength range associated with the first region 302′ or the second region 302″, the regions 302 will absorb approximately the entire spectral power distribution, no light will be scattered, and the regions will be generally less noticeable.

It is appreciated that in a spectral power distribution, lower levels of light within the scatter wavelength ranges associated with each of the regions 302 may be present, even when not intentionally emitted by the lighting system 200. Accordingly, where the lighting system 200 causes the plurality of lighting devices 202 to emit polychromatic light having a peak within its spectral power distribution within a scatter wavelength range associated with one of the first region 302′ or the second region 302′, or both, the region 302 with that scatter wavelength range will be generally more apparent, noticeable, and accented than when the spectral power distribution does not include such a peak, but does still include a relatively lower level of light within the scatter wavelength range.

In some embodiments, the lighting system 200 may include a controller 204 configured to selectively operate the plurality of light sources 202. Furthermore, the controller 204 may be configured to operate the plurality of light sources 202 so as to selectively emit light having a wavelength within the scatter wavelength range of one of the first region 302′ or the second region 302″, or both. Furthermore, the controller 204 may be configured to operate the plurality of light sources 202 to emit a first polychromatic light including within its spectral power distribution a wavelength within a wavelength range associated with the first region 302′, and a second polychromatic light including within its spectral power distribution a wavelength within a wavelength range associated with the second region 302″. In this way, the controller 204 may selectively make more prominent to an observer the first region 302′, the second region 302″, or both, by causing the plurality of light sources 202 to emit a polychromatic light to include a wavelength within the respective scatter wavelength ranges.

In some embodiments, the lighting system 200 may further include a memory 206 in electronic communication with the controller 204. The memory 206 may contain an electronic file that is accessible and readable by the controller 204. The electronic file may include one or more instructions that may be read by the controller 204 that may then cause the controller 204 to operate the plurality of light sources 202 in accordance with the instructions. The instructions may include commands to operate one or more of the plurality of light sources 202 to emit polychromatic light such that the spectral power distribution of the polychromatic light includes or excludes light within a wavelength range associated with a scatter wavelength range of one or both of the first region 302′ and the second region 302″. Moreover, the instructions may provide a sequence of commands to thusly operate one or more of the plurality of light sources 202 so as to accent and make more noticeable the sequence represented in the first and second regions 302′, 302″. For example, the instructions may include a sequence of wavelengths to be emitted including a first wavelength and a second wavelength. The controller 204 may then determine a first polychromatic light comprising a plurality of wavelengths to be emitted by the plurality of light sources 302 including the first wavelength and excluding the second wavelength. The controller 204 may then operate the plurality of light sources 302 to emit the first polychromatic light. The controller 204 may then determine a second polychromatic light comprising a plurality of wavelengths including the second wavelength and excluding the first wavelength. The controller 204 may then operate the plurality of light sources 302 to emit the second polychromatic light. It is appreciated that the instructions may contain any number of wavelengths in a sequence, and a corresponding number of polychromatic lights including one or more of the wavelengths in the sequence may be determined by the controller 204.

In some embodiments, where one or both of the regions 302 are shaped to represent an object, character, ideogram, numeral, or image, when the polychromatic light includes light within the scatter wavelength range of that region 302, the represented object, character, ideogram, numeral, or image will become highlighted, more apparent, noticeable, and accented. As a result, an observer will be more likely to observe and recognize the object, character, ideogram, numeral, or image when the polychromatic light includes light within the scatter wavelength range. Moreover, where the regions 302 include sequential representations, the sequence of those images may similarly be observable.

For example, referring now to FIG. 2, the first region 302′ may be configured into the shape of a numeral, for example, the number 1. Similarly, the second region 302″ may be configured into the shape of another numeral, such as the sequential number 2. When the polychromatic light includes within its spectral power distribution a wavelength within the scatter wavelength range associated with the first region 301′, the first region 301′ will be more prominent to an observer. Accordingly, the number 1 will be more prominent to an observer. Furthermore, if the polychromatic light also includes light within its spectral power distribution a wavelength within the scatter wavelength range associated with the second region 302″, the second region 302″ will similarly be more prominent, and an observer may more readily see the number 2. The polychromatic light may include both wavelengths associated with the scatter wavelength ranges of the respective regions 302 simultaneously, or it may include them successive or otherwise sequential polychromatic lights, requiring the polychromatic light to vary with time. In this way, any type of sequence, be it a sequence of numbers, letters to form a word, or sequences of images to simulate motion, may be made more prominent across the layer 300.

Furthermore, it is appreciated that the regions 302 may be positioned such that the sequence may be oriented to proceed in any direction across the layer 300. For example, the regions 302 may be positioned such that the sequence progresses laterally, vertically, or in any other geometric configuration, such as a sinusoidal wave, stair-step, a circle, and any other orientation. This list is exemplary only and does not limit the scope of the invention.

In some embodiments, the layer 300 may further include non-accented regions 306 positioned on the layer 300 generally surrounding the regions 302. The non-accented regions 306 may be configured to facilitate the making more prominent and noticeable the regions 302 when the associated scatter light wavelength is incident thereupon. Moreover, the non-accented regions 306 may be configured to make the regions 302 generally less prominent or noticeable when the associated scatter light wavelength is not present. The non-accented regions 306 may be generally amorphous, random, pseudo-random, or otherwise not recognizable by an observer to be recognizable as an object, character, ideogram, numeral, or image.

Referring now to FIG. 3, another embodiment of the present invention is depicted. In this embodiment, the layer 300 includes a plurality of regions 302, namely a first region 302′, a second region 302″ and third region 302′″, and a fourth region 302″″. Similar to the regions described above, the regions 302′, 302″, 302′″, 302″″ of FIG. 3 may each have an associated surface scatter profile configured to reflect, scatter, diffusively reflect, or otherwise redirect light incident thereupon that is within a scatter wavelength range or is a scatter wavelength. All light having a wavelength outside the scatter wavelength range or that is different from the scatter wavelength are absorbed.

The third region 302′″ may be generally adjacent the first region 302′, and the fourth region 302″″ may be generally adjacent the second region 302″. Additionally, the third region 302′″ may have a surface scatter profile that is configured to scatter light within a scatter wavelength range that is about the same as a scatter wavelength range of the first region 302′, or it may be different from the scatter wavelength range of the first region 302′. Similarly, the fourth region 302″″ may have a surface scatter profile that is configured to scatter light within a scatter wavelength range that is about the same as a scatter wavelength range of the second region 302″, or it may be different from the scatter wavelength range of the second region 302″. Where the first and third regions 302′, 302′″ have scatter wavelength ranges that are about the same, when light within that range is present, due to their close proximity, both the first region 302′ and the third region 302′″ will scatter the light as described above and become accented or otherwise more prominent. Where the first and third regions 302′, 302′″ have scatter wavelength ranges that are different, one or both of the first and third regions 302′, 302′″ may be made more prominent by a polychromatic light containing a wavelength within the scatter wavelength range of one or both of the first and third regions 302′, 302′″, i.e. one polychromatic light may include a wavelength within the scatter wavelength range of one of the first and third regions 302′, 302′″, and a second polychromatic light may include two wavelengths, one within the scatter wavelength range of the first region 302′, and the other within the scatter wavelength range of the third region 302′″. Accordingly, the first and third regions 302′, 302′″ may be selectively accented. The same may be accomplished with the second and fourth regions 302″, 302″″.

Referring now to FIG. 4, an additional embodiment of present invention is depicted. The present embodiment may include a system 400 comprising a lighting system 500 and a layer 600, substantially as described for the embodiment depicted in FIGS. 1-4. However, in the present, the layer 600 includes regions 602, namely a first region 602′ and a second region 602″, which are configured to have approximately identical surface scatter profiles that are configured to scatter light within a scatter wavelength range. Additionally, the first region 602′ and the second region 602″ may be positioned on the layer 600 so as to be spaced apart.

Still referring to FIG. 4, the lighting system 500 may include a first light source 502 and a second light source 504. The first light source 502 may be positioned such that light emitted by the first light source 502 is incident upon the first region 602′ but is not incident upon the second region 602″. Similarly, the second light source 504 may be positioned such that light emitted thereby is incident upon the second region 602″ but not upon the first region 602′. The lighting system 500 may further include a controller 506 configured to selectively operate each of the first light source 502 and the second light source 504 independently of each other. Furthermore the controller 506 may be configured to operate each of the first and second light sources 502, 504 to emit polychromatic light. Yet further, the controller 506 may be configured to operate each of the first and second light sources 502, 504 such that, in a first instance, the first light source 502 emits a polychromatic light having a spectral power distribution including a wavelength within the scatter wavelength range of the first and second regions 602′, 602″, and the second light source 504 emits a polychromatic light having a spectral power distribution not including a wavelength within the scatter wavelength range of the first and second regions 602′, 602″. Because light emitted by the first light source 502 is incident upon the first region 602′ and not the second region 602″, only the first region 602′ scatters the lighting within the scatter wavelength range and, hence, is made more prominent or noticeable.

Furthermore, the controller 506 may be configured to operate each of the first and second light sources 502, 504 such that, in a second instance, the first light source 502 emits a polychromatic light having a spectral power distribution not including a wavelength within the scatter wavelength range of the first and second regions 602′, 602″, and the second light source 504 emits a polychromatic light having a spectral power distribution including a wavelength within the scatter wavelength range of the first and second regions 602′, 602″. Because light emitted by the second light source 502 is incident upon the second region 602″ and not the first region 602′, only the second region 602″ scatters the lighting within the scatter wavelength range and, hence, is made more prominent or noticeable.

The lighting system 500 may further include a memory 508 substantially as described above. The memory 508 may include instructions that are readable by the controller 506 that may include a sequence of wavelengths that may be used by the controller 506 to generate a sequence of polychromatic lights including one or more of the sequence of wavelengths that may be scattered by one or more of the regions 602.

Referring now to FIG. 5, another embodiment of the present invention is now depicted. Some embodiments may include a lighting system 700 and a layer 800. The lighting system 700 may be substantially as described above, including a plurality of light sources 702 capable of emitting polychromatic light and a controller 704 coupled to each of the plurality of light sources 702 so as to control their emission.

The layer 800 may include one or more appliqués 802 attached to a surface 900. The appliqués 802 may be functionally similar to the regions 302, 602, described hereinabove, namely, have a scatter profile configured to diffusively scatter light within a scatter wavelength range and absorb light outside the scatter wavelength range. Similar to above, the appliqués 802 may be configured to wave scatter wavelength ranges that are approximately the same or are different. In some embodiments, the layer 800 may include a first appliqué 802′ and a second appliqué 802″. Additionally, the surface 900 may be configured to absorb light within the scatter wavelength range.

The appliqués 802 may be configured into a shape as described hereinabove for the regions 302, 602. Additionally, the appliqués 802 may be configured into shapes corresponding to a sequence or series. Furthermore, the appliqués 802 may be positioned about the layer 800 in any geometric configuration, as described hereinabove.

The layer 800 may further include a cover layer 804. The cover layer 804 may be positioned so as to generally cover the surface 900 and the appliqués 802. Where the cover layer 804 is so positioned, in order for any light to be incident upon the appliqués 802, it must traverse through the cover layer 804. Accordingly, the cover layer 804 may be configured to be transparent, translucent, or otherwise permit the traversal of light therethrough. In some embodiments, the cover layer 804 may be transparent to the entire spectrum of light. In some embodiments, the cover layer 804 may be transparent to only a portion of the spectrum of light, such as, for example, the visible spectrum, the infrared spectrum, and the ultraviolet spectrum. Furthermore, in some embodiments, the cover layer 804 may be configured to be transparent to a portion of the visible spectrum. In some embodiments, the cover layer 804 may be transparent to one or more portions of the visible spectrum corresponding to one or more scatter wavelength spectrums associated with the appliqués 802. For example, if the first appliqué 802′ and the second appliqué 802″ have scatter wavelength spectrums that are approximately equal, the cover layer 804 may be transparent to light within the scatter wavelength spectrum. As another example, where the first appliqué 802′ has a scatter wavelength range that is different from that of the second appliqué 802″, the cover layer 804 may be transparent to light within the scatter wavelength ranges of each of the first appliqué 802′ and the second appliqué 802″.

Moreover, in some embodiments, the cover layer 804 may include a first section 804′ associated with and positioned so as to generally cover the first appliqué 802′ and a second section 804″ associated with and positioned so as to generally cover the second appliqué 802″. The first section 804′ may be configured to be generally transparent to light within a wavelength range corresponding to the scatter wavelength range of the first appliqué 802′, and the second section 804″ may be configured to be generally transparent to light within a wavelength range corresponding to the scatter wavelength range of the second appliqué 802″.
